Regional Differences of Densitometric and Geometric Parameters of the Third Metacarpal Bone in Coldblood Horses – pQCT Study.

Abstract: The aim of the study was to analyse selected densitometric and geometric parameters in the third metacarpal bone along the long axis in horses. The densitometric parameters included the cortical and trabecular bone mineral density, while the geometric parameters included the cortical, trabecular, and total areas, strength strain index X, strength strain index Y, and the polar strength strain index. Methods: The parameters were analysed using eight sections from 10% to 80% of the length of the bone. Peripheral quantitative computed tomography was used in the study. Statistical analysis was carried out using the Friedman analysis of variance and tests. Results: The proximal metaphyseal region showed the highest predicted resistance to bone fractures in the transverse (back-front) plane, the distal metaphyseal region had the highest predicted resistance to transverse and torsional fractures in the transverse (side-side) plane. The cross-sectional area and the shape of the cross-section of the cortical bone of the MCIII had the highest coefficient of variation. The density of the cortical bone was least variable. Conclusions: The cortical area and cortical bone mineral density assumed the highest values in the diaphyseal region, while the highest total area, trabecular area and trabecular bone mineral density values were obtained in the metaphyseal proximal and distal region.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research investigates the differences in bone density and geometry along the third metacarpal bone in horses, revealing that these factors vary significantly along the bone’s length. The findings might help better understand the bone’s resistance to fractures.

Research Methodology

  • The objective was to examine various densitometric (bone density related) and geometric (shape related) parameters within the third metacarpal bone in horses. These horses were of the Coldblood breed.
  • The densitometric parameters considered were the density of the cortical and trabecular bone. The geometric parameters taken into account were measurements related to various areas and strengths of both the cortical and trabecular bone, as well as the total bone.
  • Eight sections of the bone were analyzed, from 10% to 80% of the bone’s length.
  • The process involved the use of peripheral quantitative computed tomography, a technique that provides detailed images of the measured sites, enabling accurate determination of the parameters.
  • Statistical analysis was conducted using Friedman’s analysis of variance tests, which are utilized for comparing more than two paired groups.

Research Results

  • The results showed that the bone’s proximal metaphyseal region (near the ends) exhibited the highest projected resistance to fractures in the transverse (back-front) plane.
  • The distal metaphyseal region (farthest from the center) displayed the maximum predicted resistance to transverse and torsional fractures in the side-side plane.
  • The variations in cross-sectional area and shape of the cortical bone were found to be maximum, while the density of the cortical bone varied least.

Conclusions

  • The study concluded that the cortical bone area and its density held the highest values in the diaphyseal region (middle ‘shaft’ area), while the maximum total area, trabecular area, and trabecular bone mineral density values were found in the metaphyseal proximal and distal regions, near the ends of the bone.
  • These findings can contribute to a better understanding of the structural properties of horse bones, which may further inform decisions on horse health and treatment strategies related to bone fractures and conditions.
